Front cover of the U.S. Lighthouse Establishment Lighthouse Tender
Log Book from the U.S.S. Amaranth.

This is a log book from the lighthouse tender U.S.S. Amaranth which
serviced lighthouses in the 10th District of the Lighthouse Service. Log
books were kept up to date with current information, travels and notes of
work performed at different stations.

Notes in the log book denotes
arrival and departure times, lighthouse passed, weather conditions and other
relevant information. Notes on when and where service personnel were dropped
off to perform work related tasks and picked up later that day are noted in
the log book. Just like a lighthouse station all information was to be
recorded not only to prove the work they did but to see how long it took for
future reference.

Here is a sample excerpt from September 19th, 1901:

"Left Detroit at 10:30 A.M. with W.J Beyer, Mrs. Stoddard and two
children on board, had a fine run up the river with no mishaps, passed Fort
Gratiot Light at 5:17 P.M. Wind N.E. light, weather clear. Passed Sanilac
7:55 P.M., Sand Beach 10:27 P.M., weather cloudy, wind shifted to the S.E.,
very light."
